Quote from Shanb:
How are you "looking at statistics"? Are you running it on a set of data or manually going back through? What instruments and how how far back is the data?
First thing I did was reduce the universe of stocks to a manageable number:
$15-100, DailyATR(20) > .75, averagevolume(30) >1,500,000
THen I had an intraday indicator created for TS that had inputs available for OR timeframe, # of days back to look at, and other criteria.
I used anywhere from 75-100 trading days as a lookback period (anymore isnt relative from a daytrding perspective I think. Correct me if I am wrong. The idea is to have a large enough sample size, but not too far back where its looking at environments that arent relative to what is happening recently)
I then had it tell me:
1) how many of those days was the OR/dailyATR ratio (an input is there to specify how many days for the atr is used)
less than .25 (using .25 as an example. its another input)
2) for each day that fulfilled THAT criteria, what % of THOSE days did the stock gain OR lose x% at some point in the day.
(I later changed #2 to not work on a % move comparison, but on a % of that denominator as a move.. (ie open + 65% of the daily ATR, and open - 65% of the ATR.
Regardless of the crtieria you determine to be a comparison for a"move" it was giving me an idea of what had happened behaviorally with stocks and the OR.
What I found was this. With an OR of 4 minutes, you obviously had a higher occurence of a tighter range (obviously) than 8 minutes. But you usually when that happened, 30-45% of the time it reached 3.5% - 4% intraday move..
(and this was after sorting results to most favorable, and focusing on that small portion)
Using 65% of the daily ATR, it was even less. The reason I stopped using the % move is that often % moves were too close to my "A levels", so I thought using a % of the ATR might make more sense.
After reviewing this for a bit, it does seem like low OR/ATR ratios arent that useful for finding moves.
However, I do think that tight OR's DO seem helpful in keeping a favorable risk reward setup. So if that is the intent, then yes it can be useful. I do believe that this info probably be used to find a strategy that works around keeping a favorable R/R, I just havent come up with it yet...
I am in the process now of coming up with a 30 day numberline, but dont know how feasible it is.. I have to talk to the programmer I know b/c coming up with that is way over my head from a programming perspective..
I am also trying to incorporate weekly, and monthly levels into my planning, as well as comparing how certain stocks are behaving relative to the overall market. Both things people on this thread (mainly Mav) have mentioned. I am using both 10 day relative strength, and intraday RS vs the S&P for that.
My biggest problem is that I am trying to work on many variables at once. I realize this lol.
